how to open "other" tracks in BTB for learning?

[kloijhi]

hi. as title says
I would love to take a look on other tracks, how they are built, to learn stuff.
But it seems BTB (steam) version can open only my projects. from RX_Content folder. BTB evend dont have browse option.
Any advice?

You have to move someone's project into your own folder. No, there is no internet browsing. Yes, it has to be a BTB project and not a game's track.
